As a single woman who works with many single women, I can tell you about some issues and perceptions. Many single women are single parents. Their hot button issues are childcare and making ends meet (affordable insurance, affordable power, affordable gasoline, affordable food.)
They would characterize the Republican party as facilitating the lives of the rich and famous they read about in People magazine or watch on tv. It does not make sense to them that the Republican party would seemingly support raising taxes on them while protecting the wealthy who have so much. The Republican party also wants to cut funding to the safety net that supports them.
They are drawn to things that make them feel secure in a non-violent world, because part of them is occupied in nurturing children. They want wars to cease and they want guns to be taken from private persons.
Some are likely care givers to elderly parents. They want some help out with that - affordable care, respite care, etc.
They are more likely to have had low paying jobs and have not put aside retirement savings. They want to know that they have a secure future and won’t be abandoned in age.
That is why they call the social issues “women’s issues.”
Sounds as though almost all of these single woman problems are because they are unmarried with children.
So they want government to support and protect them.
That is not the government’s duty.
